Patch by Dennis Filder <d.filder@web.de> for dsniff >= 2.4b1 to resolve naming
collision due to libpcap API changes. Dsniff was written with a function named
pcap_init() that predates the one in libpcap and is entirely different. This patch
renames it out of the way. For some more information, please have a look to Debian
bug ID #980588.
